You already know that STEM learning is everywhere these days. The term “STEM” had its origins in the 1990s at the National Science Foundation. Since then, it has become a buzzword for all sorts of events, policies, or programs involving one (or several) of the acronym’s disciplines—namely, Science, Technology, Engineering, or Math.

STEM has been in the news ever since. Below we’ve collected an assortment of articles looking at some of the challenges, successes, plans, and controversies related to this important skill set.

Do we really need to teach STEM skills to our students? Absolutely! Science, technology, engineering and math are all around us. It’s crucial to help our students recognize how these areas impact their daily lives. Aside from the benefit of being science-literate, they’ll also develop a broader idea of the world around them.

Videos do an amazing job of explaining complex ideas. We hope you’ll enjoy and share these videos. And if you find other worthy STEM videos, please let us know in the comments section below!
